Many people suffer from underarm odor and feel uncomfortable because of it. When people sweat, the fluid mixes with bacteria on the skin, which dries out and often causes an unpleasant odor. Stress, physical activity, high temperatures, and strong-smelling foods are all causes of sweating. So "does eating a lot of garlic cause underarm odor?" is a question that many people are concerned about.

Sweat glands are found all over the body, but are most abundant on the forehead, armpits, palms, and feet. When a rise in temperature is detected, sweat is secreted to cool the skin and reduce the body's internal temperature. Therefore, sweat glands under the skin are essential in keeping the body temperature stable.
